OSX package script: cabal init before update.
Update copyright notices for 2014, add missing notices
Org reader: refactor #+BEGIN..#+END block parsing code
Org reader: Support arguments for code blocks

The general form of source block headers
(`#+BEGIN_SRC <language> <switches> <header arguments>`) was not
recognized by the reader.  This patch adds support for the above form,
adds header arguments to the block's key-value pairs and marks the block
as a rundoc block if header arguments are present.

This closes #1286.
Org reader: Fix parsing of blank lines within blocks

Blank lines were parsed as two newlines instead of just one.
Thanks to Xiao Hanyu (@xiaohanyu) for pointing this out.

Org reader: Fix block parameter reader, relax constraints

The reader produced wrong results for block containing non-letter chars
in their parameter arguments.  This patch relaxes constraints in that it
allows block header arguments to contain any non-space character (except
for ']' for inline blocks).

Thanks to Xiao Hanyu for noticing this.
